235 FNUS63 KFSD 300857 RFDFSD Rangeland Fire Danger Statement National Weather Service Sioux Falls SD 357 AM CDT Tue Sep 30 2025 .DISCUSSION... Mostly dry conditions, well above average temperatures, and breezy afternoon/evening winds continue through most of the work week. High temperatures ease back into the lower to mid 80s today and Wednesday, but rebound into the upper 80s to around 90 again Thursday and Friday. Humidity values remain above critical levels with increasing dew points leading to minimum RH values generally between 30 and 45%. Most of the week will see the lowest humidity (east of I-29) offset from the stronger southerly wind gusts (west of I-29). As fuels continue to cure with the unseasonable heat and lack of sufficient rainfall, locally elevated fire weather concerns may expand. Be aware of your local conditions and use caution to avoid unintended spark in drier fuels. SDZ050-057-301200- Gregory-Brule- ...HIGH FIRE DANGER...
